Thermolysis of Methanolic Solutions of Acetyl Propionyl Peroxide

摘要

Kinetic measurements by ~1H NMR spectroscopy and chemically induced nuclear polarization (CIDNP) effects were used to study thermolysis of solutions of acetyl propionyl peroxide in methanol-d4. It is found that the thermolysis may occur both by radical and by nonradical mechanisms. A scheme of the thermolysis is proposed. Parameters of the Arrhenius equation for the rate constants of the decomposition of the peroxide and the decarboxylation of acyloxyl radicals are obtained.
